Regarding #8184, we aren't using
micromatchfor paths, just basic*/**substitution now. For anything more complicated we will recommend using a regex/.jsconfig. Fixed a bug in the stage presets (#8307), so we just removed the requirements for setting options in the meantime for ease of use. We are removing the Stage presets next release. #8293

Deprecating the yearly/stage presets in v7 (will remove next beta). Ran npm deprecate on @babel/preset-es2015, @babel/preset-es2016, @babel/preset-es2017, @babel/preset-stage-0, @babel/preset-stage-1, @babel/preset-stage-2, @babel/preset-stage-3 only for versions >v7.0.0-beta.52. This means this will only break your build if you are using ^ in Babel v7 beta (which we have recommended against each release). (It is unfortunate that the default behavior of npm is to use ^ when using npm install though; haven't made an RFC for it yet).
Also various bugfixes, change to force the pipeline plugin to have an option.
The pipeline plugin must be configured with the minimal option. This is so people explicitly know the implementation that is being used, and someone will be able to implement and test out the other proposal options. After all, this proposal is in Stage 1 still and the semantics are being figured out: this is a great opportunity to specify via the config what people are using.

@babel/polyfillto not throw an error but a warning if it is imported multiple times. Also introduce another entry point without the warning - Change how Babel handles config files regarding a lot of cases, especially for compiling
node_modules. Introducebabel.config.js- If you are using a monorepo an a single
.babelrc, you will need to change tobabel.config.jslike Babel itself is doing (#7784)

Had a bug with peerDeps, moving changelog to beta.5
Update from beta.2 -> beta.3 looks like this: #6488
Wanted to get this release out first, but next release we should make necessary breaking changes for later: using peerDeps on babel-core so that people don't install incompatible versions of plugins/babel itself and get weird errors reported, using scoped npm packages like
@babel/coredue to issues with npm squatting, knowing what is an official package or not, etc, and renaming proposal plugins tobabel-plugin-proposal-xinstead ofbabel-plugin-transform-x

const obj = {
foo: {

},
},
};
const baz = obj?.foo?.bar?.baz; // 42
const safe = obj?.qux?.baz; // undefined
// Optional chaining and normal chaining can be intermixed
obj?.foo.bar?.baz; // Only access `foo` if `obj` exists, and `baz` if
// `bar` existsfunction Foo() {
console.log(new.target);
}
Foo(); // => undefined
new Foo(); // => Foo
- better
for ofoptimization (if inferred array)
// these kinds of scenarios will compile to a regular for loop
const x = [];
for (const y of x) {}
const arr = Object.entries(x);
for (const y of arr) {}- loose mode for classes is a lot looser
Input
class A {}Output (loose)
let A = function A() {}; // looseOutput (normal)
function _classCallCheck(instance, Constructor) { if (!(instance instanceof Constructor)) { throw new TypeError("Cannot call a class as a function"); } }
